When the above scheme is implemented, when loading and unloading the Swiss machine, the workpiece is usually placed on the material rack on one side of the Swiss machine, and then the workpiece is clamped and installed on the fixture of the Swiss machine by the robotic arm for processing. Since multiple workpieces are usually placed on the material rack in a flat manner, the robotic arm needs to move a large range when clamping materials at different positions on the material rack, affecting its loading efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide an automatic loading device for a Swiss-type lathe to address the above technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic loading device for a Swiss-type lathe, comprising:

[0007] A conveying assembly, used for conveying the stacked workpieces, wherein a robotic arm assembly is provided on one side of the conveying assembly;

[0008] A top extension plate, which is arranged at the output end of the conveying assembly, and a telescopic member is installed at the bottom of the top extension plate;

[0009] The flip loading mechanism includes a flip seat placed above the top extension plate, a positioning cylinder 1 fixed on the top of the flip seat, and a positioning cylinder 2 fixed on the bottom of the flip seat and corresponding to the positioning cylinder 1. The outer ring of the positioning cylinder 1 is embedded with multiple elastic locking blocks 1 along its axial direction, and the outer ring of the positioning cylinder 2 is embedded with multiple elastic locking blocks 2 along its axial direction.

[0010] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, the installation positions of the positioning cylinder one and the positioning cylinder two on the flip seat correspond to the hole positions on the workpiece, and the ends of the positioning cylinder one and the positioning cylinder two are provided with arc chamfers. When the workpiece is pushed upward by moving the top extension plate upward, the positioning cylinder one and the positioning cylinder two with arc chamfers can be accurately plugged into the hole positions on the workpiece, thereby achieving the purpose of installing and fixing the workpiece and facilitating the loading of the workpiece.

[0011] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, a mounting bracket is fixed on the shell of the conveying component, the flip seat is rotatably connected to the mounting bracket, and a driving member 1 whose output end is connected to the flip seat is installed on the mounting bracket. By setting the mounting bracket, the height of the flip seat can be limited, so that each time the workpiece is flipped, it can be flipped to a specified position, and the flip seat is driven to rotate by the driving member 1, so that the workpiece limited at the bottom of the flip seat is flipped to the upper end, thereby achieving the purpose of automatic control.

[0012] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, the elastic locking block 1 and the elastic locking block 2 are both made of rubber, the spacing between adjacent elastic locking blocks 1 is the same as the height of the workpiece, and the spacing between adjacent elastic locking blocks 2 is the same as the height of the workpiece. When the stacked workpiece is plugged into the positioning cylinder 1, the elastic locking block 1 on the positioning cylinder 1 abuts against the corresponding workpiece to fix the workpiece. Similarly, when the stacked workpiece is plugged into the positioning cylinder 2, the elastic locking block 2 on the positioning cylinder 1 abuts against the corresponding workpiece to fix the workpiece.

[0013] As a preferred embodiment of the automatic loading device of the Swiss-made lathe provided by the present invention, a control cavity 1 is provided in the middle of the positioning cylinder 1, and a control cavity 2 is provided in the middle of the positioning cylinder 2. An adjusting rod is inserted in each of the positioning cylinders 1, and the lower end of the adjusting rod extends to the control cavity 2 of the positioning cylinder 2 corresponding to the positioning cylinder 1. When the adjusting rod moves in the inner cavity of the positioning cylinder 1 and the positioning cylinder 2, when the adjusting rod abuts against the elastic locking block 1 or the elastic locking block 2, the outer wall of the elastic locking block 1 or the elastic locking block 2 will be controlled to expand, and the outer wall diameter of the elastic locking block 1 or the elastic locking block 2 will be increased. Conversely, when the adjusting rod is not abutting against the elastic locking block 1 or the elastic locking block 2, the outer wall of the elastic locking block 1 or the elastic locking block 2 will shrink, and the outer wall diameter of the elastic locking block 1 or the elastic locking block 2 will be reduced.

[0014] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, the wall thickness of the elastic locking block one is greater than the wall thickness of the positioning cylinder one, and the wall thickness of the elastic locking block two is greater than the wall thickness of the positioning cylinder two. When the adjusting rod is inserted into the positioning cylinder one and abuts against the inner wall of the elastic locking block one, the elastic locking block one is pushed to expand outward, and the outer diameter of the expanded elastic locking block one is greater than the outer diameter of the positioning cylinder one. Similarly, when the adjusting rod is inserted into the positioning cylinder two and abuts against the inner wall of the elastic locking block two, the elastic locking block two is pushed to expand outward, and the outer diameter of the expanded elastic locking block two is greater than the outer diameter of the positioning cylinder two, so that the workpiece located on the positioning cylinder one or the positioning cylinder two can be locked more stably.

[0015] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, the upper and lower ends of the adjusting rod are provided with arc chamfers, and the outer ring of the adjusting rod is coated with grease to facilitate the stable up and down movement of the adjusting rod, and is inserted into the elastic locking block one and the elastic locking block two.

[0016] As a preferred embodiment of the automatic loading device of the Swiss-made lathe provided by the present invention, the outer wall of each adjusting rod is provided with a regulating groove along its axial direction, and a regulating wheel is correspondingly provided in each regulating groove, and multiple regulating wheels are linked to each other through a linkage assembly, and a driving part 2 is installed on the linkage assembly, and the linkage assembly and the driving part 2 are installed in the mounting position on the flip seat, and the linkage assembly is driven to work by the driving part 2, and the linkage assembly controls the rotation of multiple regulating wheels, and the regulating wheels roll with the regulating grooves on the corresponding adjusting rods, thereby controlling the up and down movement of the adjusting rods, which is convenient for the simultaneous linkage control of multiple adjusting rods. In addition, the linkage assembly is a connecting rod and gear structure, which controls the rotation of the connecting rod through the driving part 2, and drives the multiple regulating wheels to rotate through the gear assembly, so as to realize the control of multiple regulating wheels to rotate forward or reverse at the same time.

[0017] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, a limiting block is fixed at one end of the top extension plate away from the output end of the conveying component, and the limiting block is in contact with the side edge of the workpiece transferred to the top extension plate. By setting the limiting block, when the stacked workpiece is transferred to the top extension plate, it will be in contact with the limiting block, and the position of the workpiece is limited by the limiting block, so that when the top extension plate drives the workpiece to move upward, it will be plugged into the corresponding positioning cylinder one or positioning cylinder two.

[0018] As a preferred embodiment of the automatic loading device of the Swiss-type lathe provided by the present invention, a guide rod is fixed to the bottom of the top extension plate, and the guide rod is vertically plugged into the shell of the conveying assembly. By setting the guide rod, it is convenient to control the stable vertical movement of the top extension plate and connect the workpiece with the corresponding positioning cylinder one or positioning cylinder two.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The workpiece is fixed in place by the positioning cylinder 2 or the positioning cylinder 1, thereby ensuring the stability of the workpiece. When the workpiece is stacked vertically and fixed by the corresponding positioning cylinder 2 or the positioning cylinder 1, the mechanical arm assembly on one side of the Swiss machine assembly clamps the stacked workpieces in turn. Since the workpieces are stacked and arranged, the overall movement of the mechanical arm assembly is small during the clamping and loading process, thereby achieving fast loading and fixing by the positioning cylinder 2 or the positioning cylinder 1. When the Swiss machine assembly and the mechanical arm assembly are installed, a smaller space can be planned for installation, thereby improving the utilization rate of the factory space.

[0021] 2. The present invention provides an automatic loading device for a Swiss-type lathe. When the positioning cylinder drives the workpiece to flip upward, the top extension plate pushes the workpiece upward and plugs into the positioning cylinder. When the robotic arm assembly clamps the workpiece on the positioning cylinder, the adjusting rod is controlled to move downward along the inner cavity of the regulating cavity. The top of the adjusting rod is gradually separated from the corresponding elastic locking block. As shown in the figure, the outer diameter of the elastic locking block gradually shrinks. The elastic locking block with the shrinking outer diameter will release the limit of the workpiece, thereby reducing the resistance of the robotic arm assembly to clamping. In addition, during the downward movement of the adjusting rod, it will gradually insert into the positioning cylinder, causing the outer diameter of the elastic locking block to expand, locking the workpiece on the positioning cylinder. In addition, during the downward movement of the adjusting rod, the workpiece on the upper positioning cylinder is successively unlocked, and the workpiece on the positioning cylinder is successively locked. After the workpiece on the positioning cylinder is completely unlocked, the workpieces on the positioning cylinder are all locked. At this time, the workpiece locked on the positioning cylinder can be flipped upward by controlling the driving member, thereby improving the convenience of operation and improving efficiency.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other unless there is any conflict.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings. Example

[0038] Please refer to Figure 1-Figure 5An automatic loading device for a Swiss-type lathe comprises a conveying assembly 3, a top extension plate 6 and a flip loading mechanism 5. The conveying assembly 3 is used to convey stacked workpieces 4. The workpieces 4 are provided with holes 24 on the four corners. The workpieces 4 are stacked manually and placed on the conveying assembly 3. Each stack of workpieces 4 is gradually conveyed to the top extension plate 6 by the operation of the conveying assembly 3. The conveying assembly 3 is a conveyor belt commonly used in the prior art, and cylinders 25 are provided on both sides of the top extension plate 6. The output end of the cylinder 25 is connected to a positioning plate 26 for limiting the two sides of the stacked workpieces 4 to make them flush, so that the stacked workpieces 4 can be accurately placed at the designated position on the top extension plate 6. The top extension plate 6 is provided at the output end of the conveying assembly 3. A telescopic member 7 is installed at the bottom of the top extension plate 6. The telescopic member 7 is used to push the top extension plate 6 up and down to control the up and down movement of the workpiece 4 moved onto the top extension plate 6. A mechanical arm assembly 2 is provided on one side of the conveying assembly 3. The mechanical arm assembly 2 is used for clamping to assist in loading and unloading.

[0039] The flip loading mechanism 5 includes a flip seat 8 placed above the top extension plate 6, a positioning cylinder 10 fixed on the top of the flip seat 8, and a positioning cylinder 11 fixed on the bottom of the flip seat 8 and corresponding to the positioning cylinder 10. The outer ring of the positioning cylinder 10 is embedded with multiple elastic locking blocks 13 along its axial direction, and the outer ring of the positioning cylinder 2 11 is embedded with multiple elastic locking blocks 2 14 along its axial direction. The elastic locking blocks 13 and the elastic locking blocks 2 14 are both elastic rubber blocks and are connected to the positioning cylinder 10 and the positioning cylinder 2 11 respectively through vulcanization molding.

[0040] When the top extension plate 6 moves up, the stacked workpieces 4 are pushed up, and the workpieces 4 move up and gradually approach the positioning cylinder 2 11 at the bottom of the flip seat 8. The positioning cylinder 2 11 gradually plugs into the hole 24 on the workpiece 4, and the elastic locking block 2 14 provided on the positioning cylinder 2 11 is used to limit the workpiece 4, thereby plugging and fixing the workpiece 4 and the positioning cylinder 2 11, so that multiple stacked workpieces 4 can be quickly installed on the flip seat 8, and the flip seat 8 can be flipped by the driving member 1 9, so that the stacked workpieces 4 can be flipped upwards. The workpieces 4 are stacked vertically and are limited and fixed by the corresponding positioning cylinder 2 11 or positioning cylinder 1 10. At this time, the robot arm assembly 2 located on one side of the Swiss machine assembly 1 clamps the stacked workpieces 4 in sequence. Since the workpieces 4 are stacked, the overall movement of the robot arm assembly 2 is small during the clamping and loading process, which enables rapid loading. The workpieces 4 are limited and fixed by the positioning cylinder 2 11 or positioning cylinder 10, thereby ensuring the stability of the workpiece 4. After the workpiece 4 is flipped over, the required processing surface faces upward, and the robot arm assembly 2 can make the processing surface face the tool after loading.

[0041] In addition, when the positioning cylinder 2 11 with the workpiece 4 inserted is reversed to the upper side, the corresponding positioning cylinder 10 is flipped to the lower side. At this time, the workpiece 4 is pushed up again by the top extension plate 6 to be plugged into the corresponding positioning cylinder 10, so that the stacked workpieces 4 are loaded in sequence. In addition, the stacked workpieces 4 are flipped to the state to be processed by the flip seat 8. Therefore, when the workpieces 4 are stacked on the conveying assembly 3, the workpiece 4 can be turned upside down on the conveying assembly 3 in the opposite direction to the state to be processed, which makes it convenient to load the workpiece 4 by flipping. After the Swiss machine tool assembly 1 has completed processing of the workpiece 4, the Swiss machine tool assembly 1 is removed by the robot arm assembly 2 for unloading.

[0042] In this embodiment, the installation positions of the positioning cylinder 10 and the positioning cylinder 2 11 on the turning seat 8 correspond to the hole position 24 on the workpiece 4, and the ends of the positioning cylinder 10 and the positioning cylinder 2 11 are both provided with arc chamfers. When the workpiece 4 is pushed upward by moving the top plate 6 upward, the positioning cylinder 10 and the positioning cylinder 2 11 with arc chamfers can be accurately plugged into the hole position 24 on the workpiece 4, thereby achieving the purpose of installing and fixing the workpiece 4, making it convenient to load the workpiece 4.

[0043] Also, see Figure 2 and Figure 3 The workpiece 4 is fixed with a mounting bracket 12 on the shell of the conveying assembly 3, and the turning seat 8 is rotatably connected to the mounting bracket 12. A driving member 9 is installed on the mounting bracket 12, and the output end is connected to the turning seat 8. By setting the mounting bracket 12, the height of the turning seat 8 can be limited, so that each time the workpiece 4 is turned, it can be turned to the specified position, and the turning seat 8 is driven to rotate by the driving member 9, thereby turning the workpiece 4 limited at the bottom of the turning seat 8 to the upper end, thereby realizing the purpose of automatic control. In addition, the spacing between adjacent elastic locking blocks 13 is the same as the height of the workpiece 4, and the spacing between adjacent elastic locking blocks 2 14 is the same as the height of the workpiece 4. When the stacked workpiece 4 is plugged into the positioning cylinder 10, the elastic locking block 13 on the positioning cylinder 10 abuts against the corresponding workpiece 4 to fix the workpiece 4. Similarly, when the stacked workpiece 4 is plugged into the positioning cylinder 2 11, the elastic locking block 2 14 on the positioning cylinder 10 abuts against the corresponding workpiece 4 to fix the workpiece 4.

[0044] Preferably, Figure 2 and Figure 4As shown, a limit block 22 is fixed at one end of the top extension plate 6 away from the output end of the conveying assembly 3, and the limit block 22 is in contact with the side of the workpiece 4 transferred to the top extension plate 6. By setting the limit block 22, when the stacked workpiece 4 is transferred to the top extension plate 6, it will be in contact with the limit block 22, and the position of the workpiece 4 is limited by the limit block 22. Combined with the operator on one side, the stacked workpiece 4 can be further moved to conflict with one side of the limit block 22, and then the cylinder 25 drives the two positioning plates 26 to move toward each other, so that the stacked workpiece 4 can be accurately placed at the specified position on the top extension plate 6. When the top extension plate 6 drives the workpiece 4 to move upward, it is plugged into the corresponding positioning cylinder 10 or positioning cylinder 2 11. A guide rod is fixed to the bottom of the top extension plate 6, and the guide rod is vertically plugged into the shell of the conveying assembly 3. By setting the guide rod, it is easy to control the stable vertical movement of the top extension plate 6 and connect the workpiece 4 with the corresponding positioning cylinder 10 or positioning cylinder 2 11. Example

[0045] The automatic loading device of a Swiss-type lathe provided in the first embodiment is further optimized. Different from the first embodiment, when the workpiece 4 is plugged into the corresponding positioning cylinder 2 11 or positioning cylinder 2 11, the workpiece 4 is usually locked and limited by the elastic locking block 13 on the positioning cylinder 10 and the elastic locking block 2 14 on the positioning cylinder 2 11. In order to prevent the workpiece 4 from escaping from the positioning cylinder 10 or the positioning cylinder 2 11 during the flipping process, Figures 5-10 As shown, a regulating cavity 1 20 is provided in the middle of the positioning cylinder 10, and a regulating cavity 21 is provided in the middle of the positioning cylinder 2 11. An adjusting rod 15 is inserted in each positioning cylinder 10, and the lower end of the adjusting rod 15 extends to the regulating cavity 21 of the positioning cylinder 2 11 corresponding to the positioning cylinder 10. When the adjusting rod 15 moves in the inner cavity of the positioning cylinder 10 and the positioning cylinder 2 11, when the adjusting rod 15 abuts against the elastic locking block 13 or the elastic locking block 2 14, the elastic locking block 13 or the elastic locking block 2 will be squeezed. The outer wall of the tightening block 14 makes it protrude from the regulating cavity 1 20 or the regulating cavity 2 21, thereby increasing the outer wall diameter of the positioning cylinder 10 or the positioning cylinder 2 11 in which the elastic locking block 13 or the elastic locking block 2 14 is located. Conversely, when the adjusting rod 15 is not in contact with the elastic locking block 13 or the elastic locking block 2 14, the outer wall of the elastic locking block 13 or the elastic locking block 2 14 shrinks, thereby reducing the outer wall diameter of the positioning cylinder 10 or the positioning cylinder 2 11 in which the elastic locking block 13 or the elastic locking block 2 14 is located.

[0046] Through the above structural design, when the positioning cylinder 10 drives the workpiece 4 to flip upward, the top extension plate 6 pushes the workpiece 4 to move upward and plug into the positioning cylinder 2 11. When the robot arm assembly 2 clamps the workpiece 4 on the positioning cylinder 10, the adjusting rod 15 is controlled to move downward along the inner cavity of the regulating cavity 1 20, and the top of the adjusting rod 15 is gradually separated from the corresponding elastic locking block 13. Figure 8 As shown, the outer diameter of the elastic locking block 13 gradually shrinks, and the elastic locking block 13 with the shrunk outer diameter will release the limit of the workpiece 4, thereby reducing the resistance of the robot arm assembly 2 to clamping. In addition, during the downward movement of the adjusting rod 15, it will gradually be inserted into the positioning cylinder 2 11, and the outer diameter of the elastic locking block 2 14 will expand, locking the workpiece 4 on the positioning cylinder 2 11, and during the downward movement of the adjusting rod 15, the workpiece 4 on the upper positioning cylinder 10 is successively unlocked, and the workpiece 4 on the positioning cylinder 2 11 is successively locked, so that after the workpiece 4 on the positioning cylinder 10 is completely unlocked, the workpiece 4 on the positioning cylinder 2 11 is completely locked. At this time, the workpiece 4 locked on the positioning cylinder 2 11 can be flipped upward by controlling the operation of the driving member 19, thereby improving the convenience of operation and improving efficiency.

[0047] Preferably, Figure 7 As shown, the wall thickness of the elastic locking block 13 is greater than the wall thickness of the positioning cylinder 10, and the wall thickness of the elastic locking block 2 14 is greater than the wall thickness of the positioning cylinder 2 11. When the adjusting rod 15 is inserted into the positioning cylinder 10 and abuts against the inner wall of the elastic locking block 13, the elastic locking block 13 is pushed to expand outward. The outer diameter of the expanded elastic locking block 13 is greater than the outer diameter of the positioning cylinder 10. Similarly, when the adjusting rod 15 is inserted into the positioning cylinder 2 11 and abuts against the elastic locking block 2 14, the elastic locking block 13 is pushed outward. When the inner wall abuts, the elastic locking block 2 14 is pushed outward. The outer diameter of the expanded elastic locking block 2 14 is larger than the outer diameter of the positioning cylinder 2 11, which more stably locks the workpiece 4 located on the positioning cylinder 10 or the positioning cylinder 2 11. In addition, the upper and lower ends of the adjusting rod 15 are provided with arc chamfers, and the outer ring of the adjusting rod 15 is coated with grease, which facilitates the stable up and down movement of the adjusting rod 15 and is inserted into the elastic locking block 13 and the elastic locking block 2 14.

[0048] It is worth mentioning that Figure 6As shown, the outer wall of each adjustment rod 15 is provided with an adjustment groove 16 along its axial direction, and each adjustment groove 16 is correspondingly provided with an adjustment wheel 17. The multiple adjustment wheels 17 are linked together by a linkage assembly 18. A second driving member 19 is installed on the linkage assembly 18. The linkage assembly 18 and the second driving member 19 are both installed in the mounting position 23 on the flip seat 8. The linkage assembly 18 is driven by the second driving member 19 to operate. The linkage assembly 18 controls the rotation of the multiple adjustment wheels 17. The adjustment wheels 17 roll in the adjustment groove 16 on the corresponding adjustment rod 15. The friction between the two controls the up and down movement of the adjustment rod 15, facilitating the simultaneous linkage control of the multiple adjustment rods 15. In addition, the linkage assembly 18 is a connecting rod and gear structure. The connecting rod is controlled by the second driving member 19 to rotate, and the gear assembly drives the multiple adjustment wheels 17 to rotate, thereby controlling the simultaneous forward or reverse rotation of the multiple adjustment wheels 17. In this embodiment, the gear assembly adopts a bevel gear connection, and the two connecting rods are respectively connected to one of the bevel gears.
